You guys! My APPROVAL arrived today in the post! I'll phone tomorrow to see about booking a ceremony... It's perfect because my FIL just asked us about our plans for Christmas, so it's possible we can go to Bristol to have my ceremony and Christmas dinner in one trip! And, what a Christmas! Ahhhhhhhhhh! Soooo happy!
My NDRS+JCAP was October 24th (online application submitted the day before, on the 23rd) and biometrics submitted on October 27th. My invitation/approval letter is dated November 22 and arrived today.

ETA: I have to wait 'til tomorrow to book my ceremony because my husband is off today, and he doesn't know what days he's off next month, so we'll have to get that information when he goes in to work.
